I know of another CPU architecture that has fine-grained hardware
threads and has working qemu emulation at a useful performance for
debugging kernels, but it's not public as far as I know, and I don't
know if it's ok to name it.  I don't think it's VLIW, only that it has
lots of hardware threads and a working qemu model.
